Exercise towel



FIG. 1 is a perspective view of an exercise towel.

FIG. 2 is a top plan view of the exercise towel. The bottom view is the mirror image of and identical to the top view.

FIG. 3 is a side elevation view of the towel. The right side and left side views are identical; and,

FIG. 4 is a front side elevation view of the exercise towel. The back side view is identical to the front side.

The broken lines that appear in the figures are for illustrative purposes only and form no part of the claimed design. 

I claim the ornamental design for an exercise towel, as shown and described.
